I have run about 2-3 tanks so far, seems it runs great with the heater on and then really rich when off . Can't seem to get a happy medium as throttle opens up 1/2 way fine and then boggs down.
Have to open high speed needle to get it to run at full throttle but at that setting on the needle valve , it usually dies at low throttle settings.
I am gonna run 2 more tanks thru it tomorrow and will lean it out , ( will have to keep heater on ) /
Thanks for the reply back as I never had anything like this before.
I usually run FOX or Supertigre engs and they run out of the box.
